✨ NNPNTS ✨ — it's giving "interpolate at ONE point" 🎯

okay bestie, welcome to the NCAR GRAPHICS corner of the manual, section 3NCARG 💅 this one's a lil Fortran subroutine and she is so specific about what she does: she interpolates at a single point. not two, not a grid, not a vibe — one point. periodt. 🫶

🌸 NAME 🌸

NNPNTS — Interpolate at a single point 🎀

🦋 SYNOPSIS 🦋

CALL NNPNTS (X, Y, Z)

that's it. that's the whole call. three args, no cap. ✨

💖 DESCRIPTION 💖

here's the tea on the arguments, bestie — every single one, no skips 🍓

  • X — (Real, Input) — the X coordinate of the point where interpolation is desired. it's giving "where am I on the X axis, queen?" 📍
  • Y — (Real, Input) — the Y coordinate of the point where interpolation is desired. same energy, but Y. vertical slay. 📍
  • Z — (Real, Output) — the interpolated functional value at the point (X,Y). she doesn't come in with a value, she leaves with one. icon behavior. 👑

🌈 USAGE 🌈

so when do you even call her? literally when you want to interpolate at an individual point. that's the whole moment. 💫

but bestie, LISTEN — the order matters, fr fr:

🚨 NNPNTINITS must be called prior to calling NNPNTS. do not skip this. do not pass go. do not collect $200. 😭
🚨 and when you're done doing your single-point thing, NNPNTEND must be called to terminate single point mode. you can't just ghost her. 🙈

so the whole ritual is: NNPNTINITS → NNPNTS (as many times as your heart desires) → NNPNTEND. main character energy from start to finish. 👑

💜 ACCESS 💜

to use NNPNTS, load the NCAR Graphics library ngmath. that's the one. go get her. 🧚
